VG224 is not the limiting factor on NSE based standards based (protocol based).  It's the control protocol, where SCCP can only do NSE, and the others can do standards.

Possibly, depending how your vg224s and PSTN gateways are configured... Last I knew VG224 only supports T.38 NSE, not standards based T.38 so be careful of that. Changing the fax protocol should be a coordinated effort between the PSTN gateway and the Analog gateways to make sure nothing breaks.

Here's a good writeup on the supported fax protocols with sample configs.
