That's something I started doing some years ago (2013, when studying
smartcard programming), but then left incomplete.
The smartcards I was using supported many RSA keys and some even NFC, so
I thought to use slots for:
- 1 key for signature
- N keys for decryption (selectable by sending a special command)
- 2 keys for auth (different for contact and contactless operation)
That would have been completely transparent for GPG.
Moreover I wanted to support secure key export.
Probably a task too big for a newbie, even with the help of Petr Svenda.
You can still find the code on github:

Probably the same technique could be used for the FST-01, to make good
use of the external memory :)
BYtE,
Diego
