mersennne.org does something similar- I run ECM with B1=80k, B2=100*B1, and every 5 curves I run earns credit of 8 standard B1=50k curves. It's not a perfect conversion, but it works well enough for B1 near the expected T-level.

Where it breaks down is for B1 choices far smaller than useful- e.g. M1277; 1000 curves at B1 =1e6 are useless there, but get credited at just over 1 curve @850M. We hope people don't do that...
