WiX extension for burn / bootstrapper -

i'm using wixstandardbootstrapperapplication create bootstrapper installer using wix. in i'm using filesearch wixutilextension library (part of standard wix install). i'm not quite happy logic it's using though, , want things little differently, can't find easy way that. see options as:

create own managed bootstrapper, mean creating entire ui experience, feels awful lot of yak shaving. create own library like wixutilextension inject of own custom logic.

i favour alternative 2, given have no involvement in replacing overall process offered wixstandardbootstrapperapplication, i'm having hard time finding how create burn-centric extension. can find detail creating extensions mapped custom actions (msi only, not fire bootstrapper), or perform other pre-processing , compiler actions aren't relevant needs here.

how go creating burn extension? improve off biting bullet , creating own managed bootstrapper, or there simple alternative i'm missing here?

the closest thing want bafunctions.dll neil wrote extendedba. able merge of wix 3.8. there's illustration code in burn's samples directory.
