FT-UN starships, and improved hulls

Another idea for the skunk works I proposed a while ago, and heard
nothing
about, is improved hulls for the UN ships.

Reenforced hull

I heard a lot of discusion about UN ships having a strong hull for the
mass
of a normal hull. Because a hull now has no set strength other than a
minimum of 10%, how about this system instead?-
mass/dp as normal, but a cost of x3.
1 dp removed from 2nd row and added to the first row, +2cost
2 dp removed from 3rd row and added to the first row, +3cost
3 dp removed from 4th row and added to the first row, +4cost
This would make the ships harder to threshold check for the first
threshold,
but more vulnerable as the dammage increases. For example-
Normal ship-40DP hull, cost=80
1st row=10DP
2nd row=10DP
3rd row=10DP
4th row=10DP
Reenforced ship-40DP hull, cost=129
1st row=16DP
2nd row=9DP
3rd row=8DP
4th row=7DP
The cost are just a rough guess off the top of my head, but you could
have
double the DP`s moved to the first row for x4 hull cost etc.

I`m reposting this because I don`t think I got any replies the last
time,
and I want to see what people think. Also, the weapons archive has
caused me
to dig up some of my older or wakier ideas.
