UniSeals in a Brute sound feasible?

[GuySmilie]

Been thinking about plumbing my Brute using 1/2" UniSeals instead of conventional bulkheads.
These would be mounted in the sidewall, near the top.
Similar to the layout of jdiecks Brute.

Brutes are not all that thick and UniSeals are pretty stiff to be using in such a flimsy material like used to make Brutes.
Anyone have any learned opinion if this will give good leak-free seals?
