Double bass NAM?

I have an Ibanez UB805 electric upright that I’d like to make sound * just a little bit more* like a proper double bass (I’m playing blues, all pizz). I have a Valeton GP-50 that supports NAM impulses, and I was wondering if anyone has ever captured a double bass in NAM format? (Fwiw I have searched quite a bit and come up dry.)

I know 3 Sigma Audio has some well-lauded captures of several double basses, but those are in ACE format and $15 each, and I don’t know enough on how to convert ACE to NAM (if that’s even possible) so I’d rather not pay for impulses I can’t use without buying another pedal, especially since a lot of NAM/Snaptones are open source and free to boot.
