Hot backup? Alter tablespace dah dah dah one at a time and do the business? Yes, of course you can. And in your position, I'd feel reasonably comfortable, provided I had all the logs.

Personally, I'd shut the whole thing down now, and take a cold backup. But then, I'm a conservative old b*****. And I have **absolutely no evidence** to support this view, but I'd be nervous about combining RAC and RMAN. One or the other, yes, but these new features always seem to have issues once one tries to combine them.

But then again, as I implied, I'm a cynic (and as such I doubt that Mr. Ellison would hold me in much regard). You might be better off canvassing the views of others before heeding my advice.
