In my opinion it's like music. You have practice, rehearsals, and performances. You should only experiment with new gear+scenario combinations in practices, never in a performance.
I am a HUGE advocate for MF. If you have already shot several times in similar scenarios with MF and are completely comfortable with it then go for it - better image quality, more resolution and file flexibility, the look, the impression to the client, and unique abilities like high speed flash sync if you need it.
But if you've not shoot this equipment in this environment before I strongly encourage you to stick with what you've practiced and, if you're interested in exploring using your MF gear in the field then do so first in a practice environment (e.g. shooting your friend/family or a model who needs some portfolio shots but couldn't afford to pay you your normal rate).
I also would never willingly place myself in a situation where I was on an important gig more than 5 minutes from a source of a backup, without some form of backup in my bag. Depending on the situation, client, and your needs that could be as little as a G11 (it's by no means a "pro" body but in a crunch you could at least switch to manual exposure, raw files, and get the shot) or preferably your Nikon with a single lens, but it better be something. If you can't logistically carry the Hassy gear you want with at least a minimum backup then you shouldn't use it period (note this is not a dig at Hassy - I would say the same whether the primary camera was Hassy, Phase, Canon, Nikon or anything else; pro = backup camera).
As my music teacher always said "performances are terrible times to practice".
