Not sure if this has been suggested before...
How about expanding the Tractor Beam techs with some miniaturization?
The first level costs 5,000 RP and gives you your basic, 10 HS Tractor Beam.
The next level costs 10,000 RP and reduces the size by 3 HS, to 7 HS.
The next level costs 20,000 RP and reduces the size by 2 HS, to 5 HS.
The next level costs 40,000 RP and reduces the size by 1 HS, to 4 HS.
The next level costs 80,000 RP and reduces the size by 1 HS, to 3 HS.
The next level costs 160,000 RP and reduces the size by 1 HS, to 2 HS.
The last level costs 320,000 RP and reduces the size by 1 HS, to 1 HS.
