If you float in above the threshold a fair bit higher than Vref, is it
acceptable technique to chance the reverser to preclude landing too far
down the runway?

I've only allegedly worked on couple of different types of buckets,
all on biz-jets and they have had one thing in common.

The aircraft must have a weight-on-wheels signal present somewhere in
the logic circuit before the reversers will unlock or deploy.

Inflight, if a not-locked condition is detected, the reversers are
hydraulically driven to the stowed position and pressure is maintained
holding them there until the not-locked condition goes away.

Unless you are learning to fly the space shuttle:

having the buckets out while flying is a RBT (really bad thing), but
I'm sure there are some exceptions out there.
