I honestly believe this will be the case.
For me, i went from loving Sense (M2D port) on WinMo, then on Android (HTC Hero), then i got seriously bored of it on both WinMo & Android.
I can skin anything, so i used to skin (theme) the hell out of it. Then i stopped using, and just was satified with stock Android OS UI. I use Beautiful Widgets/Home so if i want the Sense look, it can be easily achieved.
But i wil make use of the sense.com site (for theming needs) as you can't beat the original for a base theme.
Its a great idea tho in essence as you can theme your ROMs legitimately and feel that you haven't broken anything or voided your warranty in doing so.
Be cool, be positive. You can achieve anything you want!
