I guess that - technically, anyway - what you are proposing really isn't "hrt" (hormone REPLACEMENT therapy) any more. Maybe "hat" (hormone AUGMENTATION therapy) would be a more precise term, lol.
I've been on hrt for just a few months, feel healthy for the first time in years, ready to finally get back to the gym, and I've thought about doing exactly the same thing. In my case - and I don't have health insurance, so I'm footing the bill for all of it anyway - my doctor doesn't know shit about hrt. After several weeks of nagging him to test my hormone levels, he finally did and my tests came back with total testosterone about 138! So I'm now on Androgel and it's costing me a fortune!
But here's the thing...previously, I was on heavy-duty painkillers for years. I've got a disc problem in my lower back from a previous failed lumbar surgery and four new herniated discs to boot. The surgeon told me that if it was him, he'd just stay on painkillers and forget another surgery, that no one can be sure I wouldn't come out with MORE pain!
Now docs are scared to prescribe enough painkillers to really get anybody out of pain completely, so I suffered for a lot of years. I finaly started "doctor shopping" just so I could lead a semi-normal life. I HAD to do it. The DEA and congress made a criminal out of me. But I got by...
Okay. Enter hrt. After 2 weeks, it was time to renew my scripts for hydrocodone and oxycontin. I was feeling so good and was tolerating the pain so much better that I told the doc to drop the oxycontin. I didn't want it. He couldn't believe it! He couldn't believe a long-term oxycontin user was actually asking to be taken off of it! But hell, I never wanted those damn painkillers in the first place. I just wanted a normal, pain-free existence. My script comes up again in about a week and I'm going to ask him to cut the hydrocodone back by about a third.
Having normal test levels has made it so much easier to tolerate the pain. I mean, it still hurts like hell - ALL the time. But I can now deal with it better. I feel like fighting that daily battle with the pain now - just like I used to years ago when I first got hurt. I originally went on the painkillers because I was so tired and exhausted, so depressed from facing that long daily fight against continual agony that it was either eat pills or shoot myself in the head.
I know that if I can get back in the gym and get back to lifting the heavy iron (in very controlled and careful movements, of course) that I'll feel even better. My goal is to get off the painkillers completely. Forever.
And if I have to "doctor shop" for my hormones, then I'll damn sure do it. I learned a long time ago that the laws aren't neccessarily right or just. And I learned that we have to take control of our health and well-being ourselves - especially in this area. Because doctors are more worried about keeping their license to practice, about keeping up their reputations, and about avoiding prosecution themselves than they will EVER be about you, the patient. And even endocrinologists usually don't have even half the knowledge that a well-educated and careful bodybuilder has.
I see hormone augmentation therapy, as I will now call it (cool name for it, I think) as no more wrong or unethical than breast augmentation, liposuction, makeup, "lifts" in a short guys shoes, creatine, protien shakes, or vitamins, or any form of plastic surgery. In most cases, it's a hell of a lot safer too. You might notice, if you take a second look at that short list in the previous sentence, all the most dangerous things involve doctors, lol.
Good luck with your plans. Just keep a careful log of which pharmacy you use for which prescription(s). Don't get them mixed up. That's how people get caught (going to the same pharmacy you went to last month with a script from a different doctor). The pharmacist will start calling the doctors, saying, "Hey! Did you know that so-n-so is using another doctor as well?". You may not get legally busted (although you might. I mean, it IS technically illegal and people DO get busted for it - just ask Rush Limbaugh! LOL!) But you will definately get cut off by both doctors if they find out. Good luck.
