Under the Marriott
Bonv∘y Terms & Conditions, the benefit entitlement is solely that to which the person redeeming the points (your partner) has earned.
However, there are countless FlyerTalker posts about couples in your situation being granted some higher benefits, such as breakfast, if sought politely.
However, if they say "No", there is not much one can do about it. Your mileage may vary (YMMV), meaning nothing is guaranteed.
There would not be a technological method to apply your Suite Night Awards (SNAs), though, to his account. Sorry.
A workaround to that might be to transfer points from his account to yours. One can transfer 100K points per calendar year. But then he would not receive the lifetime Elite Qualifying Nights (EQN); you would.
And check the SNA thread for insight into the likelihood of them clearing.
