A fork of Matt's proposal converted to GF(2^8) is here:
https://github.com/cetuscetus/btctool/blob/bip/bip-.mediawiki
Other changes include:
- only six application/version bytes are allocated, which is the
minimum to ensure that the encoded form starts with S in all cases;
- encoded prefixes a

I've looked at the latest draft and am worried about the increased AVB
namespace usage. Would it make sense to differentiate main/testnet in
the prefix byte instead of the AVB? Perhaps aiming for ST rather than
TS.

I like CRC16. Do you intend to use it in conjunction with a cryptographic hash?
Regarding the choice of fields, any implementation of this BIP will
need big integer arithmetic to do base-58 anyw

I need your BIP.
We are going to implement SSS and we'd rather stick with something
