I think you have to be practical when looking for 'equivalent' lenses in 8x10. Mainly because there are fewer focal lengths available for 8x10, and some of those are much rarer than others and therefore may be hard to find. Personally I would just get a 240 or a 300 based on the best deal I could get and what was available. If you get too picky you could wait a long time for the right lens at the right price.
Take a look at the series of portraits I've done with a 300mm Nikkor f5.6 and an 8x10 Deardorff.....

Really nice work and a fantastic plan!
Inspirational, I plan to try your technique as I have few targets right now in my new location.
Set up and wait!
Thanks for posting.

A larger negative will always have a larger 'm' (magnification) factor in the DOF equation.
