Yes, I've done a little experimenting with Allegro's HE sensors.

From the data sheets I have here, the typical Rise/Fall times
are in the range 100ns-400ns, which sounds like they should
suit your 60kHz app OK. Some part numbers are

A3046EU, 3056, 3058
UGN3055, 3059, 3113,3120, 3130,3140
A3121,3122,3123

There are plenty more, Allegro make a ton of them in all kinds
of flavours
