That would be a nightmare. It would break the factory presets and many of the user's presets.
The only possibility would be to change the User 2 bank to a User FR bank. So you would give up 1024 User IR slots in exchange for 32 FullRes user slots.
Very satisfied Mk1 owner here. I would gladly give up user 2 bank for more functionality and enhancements.
IMHO 2000 cab slots is overkill anyway.
