You don't like lambda? Fine, define an external function first. Then you can write:

filter(pred, (f(x) for x in seq))

There's no violation of DRY, there's no redundancy, there's no lambda, there's no "y" variable needed. What's ugly about it?

I think its great and that it kills any justification for the proposal.

I hate it. It mixes map/filter style and comprehension style; and the fact it does so in a single line only makes it worse. Not that it would be any better in two lines.
