About to start on my 6L6 PP amp but I thought I'd ask for opinions on a few things.
I have the following to play with.
400v B+
12AU7
12AX7
6SN7
6EU7
6L6
I'm quite happy with the floating paraphase inverter I used on my 6V6 PP amp but it could use a little more gain. I do like the cathodyne PI too. Any suggestions using drivers after a PI or should I just drive the 6L6s with the PI?

Cathodyne works very well and no drivers are needed.
Here is one version of 6L6 PP I have done:
An externally hosted image should be here but it was not working when we last tested it.

Would a 6SN7 work in place of the 6SL7. Gain is much lower. Or 12AT7?

The sensitivity would be quite poor with 6SN7.
If you want to use 12AT7, 6SN7, etc. then a LTP phase inverter with one voltage amplifying stage is better topology.
