Umm, requiring medical research to overturn an unjustified habit is a good way of ensuring you will never change that habit. In particular, you won't realistically find research saying "oh, harishankar's particular hunt-and-peck technique wherein you use mostly the index and middle finger, occasionally the ring finger, and never the pinkie finger? Yeah, we did a study with 500 participants and found it to be disadvantageous to the wrists." Ergonomics research is sparse as it is.
That said, there are several different ways we can try to accommodate that habit:
Most straightforward: stick with colemak, but don't use pinkies for most any key. Here's a sample of my finger chart, for instance (ignore the symbols, concentrate on the colors):
As you can see, most keys canonically used by the pinkie are instead pressed with the ring. The only "common keys" my pinkies still press are those on the home row - this can eventually help in strengthening them. Ring finger use for this option may not be as sparse as you're used to, but it should be relatively manageable (it's a reasonably strong finger, anyway).
Go for a layout (or better yet, create your own) that optimizes for your current style. As a first-order optimization, you'd want to put rare keys on the pinkie slots (so that you'd less often have to move there) and common ones all around the middle (since they're easy for your index finger to reach). The ones closest to this goal that I know of are QFMLWY or QGMLWB:
though you could still improve them by swapping the pinkie keys with a less common key. Because swapping sometimes has unintentional side effects, you might prefer QFMLWY, where you'd only have to swap the D, as a base. Alternatively, just call D/H "uncommon enough" and keep as it is.
-
A second-order optimization might be for common digraphs to be right next to one another, so that you could quickly hit them with your index and middle. Unfortunately, this would probably require designing a completely new layout, and is beyond the scope of my knowledge.
Middle ground: Touchtype using QFMLWY or QGMLWB. (Incidentally, those two are the "optimized" layouts according to carplax, so might be good to have under your sleeve anyway.)
One-handed dvorak should decrease the side-by-side distance required. Not sure what side-effects it might have, however.
All in all, I'd prefer #1 as the more "balanced" way to start practicing the pinkies. If the O or A prove too much, you can try for #3 instead.
Finally, even if you do stick with your current typing habit, that doesn't mean you have to stick with QWERTY. Indeed, it has the very common A under the left-pinkie finger, a disadvantage for your style compared to QFMLWY or QGMLWB.
