Can we get the UI changes from 2.3.3 from EVO Shift on the EVO?

My wife and I have an EVO, and an EVO Shift. Mine is the Shift.
Last night did the OTA update from Sprint which put both phones on Gingerbread 2.3.3.

Mine has a ton of new visual elements, new HTC widgets, visual changes to sms and email, the bars are skinable, etc, etc...

My wife would like to get these features on her phone as well. Is there any way to get these changes to the EVO?

Is it just HTC Sense that's different? The EVO Shift shows me that I'm on HTC Sense 2.1, but can't find the version info on the EVO.

If anyone can point me in the right direction I would appreciate it. Been a WinMo user till about 4 months ago, swore I'd never go to Android. Glad I did, but have a lot to learn! Custom ROMs seem a bit trickier than they were on my old WinMo devices... or maybe it's just because it's all new to me still.
