Pheros that have produced blatantly bisexual hits and requests for threesomes with me in just the environments you mention include:
MX297 or MX390 (same mix different scents) and TUTH or straight androstenone.
A314/P114/TUTH:
The women I was involved with at the time were 39 and 36
However, it is exactly as bosshank says above - Pheros won’t make anyone act out of their basic character and if your wife isn’t already inclined, these will not change matters.
Oh and I just remembered MX390/CTTM2 and NPA - That was a proposition I’d rather draw a veil over!
