I find it hard to understand this explanation, too many terms getting 
mixed up. As I understand it, working with UV's is slow for you, and 
so being able to work partially without in editmode before was helpful?

If that's the case, then that's really not a good argument for a 
separate UV mode. Working with 50k faces on that kind of computer 
(assuming a reasonable grahics card) should really be fast enough. If 
it's not, there is a problem somewhere that is fixable.

You can also try to investigate why it is slow for you. Like, does the 
size of the image matter? Does disabling drawing of dashed edges in 
the uv window view properties helps? Is it the 3d view or the uv 
window that draws slow (move around in both of them)? Is transforming 
in the uv window still slow with no 3d view visible?

I think there's isn't really a good key + mouse combination available. 
I can't think of nice solution, besides some option that turns the 
alt+(shift+)rmb key combinations into seam marking tools instead of 
loop selection.
