I would like something where Vassal countries who have the same religion as their overlord cannot convert (if necessary, with certain qualifications - eg, fanaticism/theocracy civic).
For immersion, it would be good to have my subjugated underlings stay under my wing after I've sent missionaries throughout their nation.
For UHVs, it would help some of the conversion goals. They could be made slightly harder (eg, x religion for 20 turns) to compensate.
