Yes, quite easily.

In the shiparch.ini file, find whatever ship you want to change. You should see a line like:
hp_type = hp_mine_dropper, HpMine01
OR
hp_type = hp_countermeasure_dropper, HpCM01

Delete those lines. Then find the lines for the weapons:

hp_type = hp_gun_special_3, HpWeapon01, etc

At the very end of the line, you should add the HpMine01 or HpCM01 to make that hardpoint accept the gun. The number after special tells what levels, and you need to add HpMine01 or HpCM01 to the level you want it to be, and all levels below.
You can also make slots take turrets, have multiple minelayers, CM, or even half a dozen thrusters.

Here's the lines for hardpoints from my modified Sabre (not sure how the formatting on this will turn out...)

Note that I have 2 shield slots...handy. There's also some extra weapon slots that you may have noticed on the ships that I'm using.
If you need help understanding all this check out the topic on modifying ship stats...it's there somewhere.

DarkJackal

as a note....i place my thrusters in the HpEngine01 - 03 slots on my anubis...but so as to remove the dumb graphic i edit the thruster to use the no_thruster graphic....looks nice...thrusters are an additive speed boost...so 3 thruster ups my speed quite a bit

my ships base speed is 100....and each thruster adds 100...total speed is 400...unfortunatly...my thruster power drains rather rapidly...but thats ok...(and yes...ive already decrease the amount of power my thruster uses...)


as another note...ive got the anubus using these slots now

shield = hpcloak01
thruster = hpengine01 02 03
mines = hpmine01
CM = hpcm01
guns = hpweapon01-06 08 torpedo01 - 03
turrets = hpshield01 hpthruster 01 - 03
torpedoes - torpedo02 03


that ends up with 10 guns (two which can be changed out for torpedoes)
4 turrets
3 thrusters
1 mine CM shield

total of 20 hardpoints....quite nice...there are a few other hardpoints that i might try and use....but all of them would probly require the removal of the graphics on risk that the ship looks stupid

Hey restricted, think I could trouble you to post a link for the files for that ship? Id really like to take that for a test drive. =)
