Spelling error. How about 'main trunk'? Sorry.

I am finishing my basement. I have a main feed truck running down the
center of the house. It looks like it can be raised up about 4 inches to
snug up against the first floor joists. I need all the headroom I can
possibly get.
.
Can this be done? Any idea on cost (I know this is an unfair question).
I am guessing I need some sort of transition boot where the duct would get
cut. Would this cut air flow if a transition was put in? I don't have
much HVAC experience, but it doesn't seem like this would be a huge job.

Thank you for your time.
