Brewed in a keg with floating dip tube. Added small dry hop charge while flowing CO2. It is cold crashing now. Plan to transfer to a purged serving keg. Question is if I can just put new wort on top of this yeast and dry hop cake? Current batch was a pale ale and the new batch will be an IPA.
Absolutely!
Yeast usually quadruples (or even more) during fermentation, so you may have quite a bit more yeast on the bottom than you'd need. You may lose some yeast expression due that, but usually it's not an issue in an IPA, they're more about the hops.
If you want, you could remove (and even save out) half to 3/4 of that yeast cake before racking your new batch on top of it.
I would try to scoop out as much of the dry hops as you can. You don't need more than about a cup of yeast for a five gallon batch so you can clean most of that out and avoid unwanted tannins from the leftover dry hops and other unintended effects.
