I'm 'more or less' (no time ATM :( ) working on extending standard GPG
card protocol to support user-controlled export of keys and ability to
keep 'n' old enc keys on the same card.

Try to find a Java card that supports longer keys...

I've only seen RSA (up to 2048bit) and ECC (some "small" fields only)
support in Java cards. Some BasicCards should support up to 4096bit (and
they're the ones used by offical GPG card, IIUC).
