License request for Bytewords and Bytemoji as MIT or ISC

[mk-pmb]

Hi! Bytewords and Bytemoji are great work and I'd like to use them! However, it seems like they are currently available only under BSD-2-Clause Plus Patent License, which isn't in the list of approved licenses for my client. Is there a way I can have (and then redistribute) them under the MIT or ISC license? Or some other well-known, commerce-friendly open source license? Also I'd need an explicit license grant, because the default in the readme requires extensive research to exclude the possibility of another license being mentioned near the relevant documents. Having to do this detective work each time would make lawyers rich but at the cost of my client.
