Well I decided to apply these costings to the 3 Reavers I used recently.
Code Sample: 
			3.15		semajnollissor
Reaver (BTS)		575		560
2x Quake Cannons 	150		150
CLP			-		15
CML			25		25 (?)
Veteran Princeps	25		25 (?)
Sacred Icon		50		50
		Total	825	        825
-
Reaver			575		560
CCW			-		30
Melta Cannon		50		50
Plasma Cannon		25		30
CML			25		25 (?)
Legate			50		50 (?)
Sacred Icon		50		50
		Total	775		795
-
Reaver			575		560
Plasma Blast Gun	-		15
Gatling Blaster		25		30
Laser Burner		-		15
CML			25		25 (?)
Veteran Princeps	25		25 (?)
		Total	650		670
-
		Total	2250		2290
I think semajnollissor’s idea 
plus the first warhound support taken must be a pack, 
plus an increase in CML to 50pts (with AP/AT attack added) would go along way to limit AMTL activations (3x cheapest Reavers @ 605pts each plus Warhound pack, plus 2 single Warhound = 6 activations with AA, Legate, Princeps, Icons etc to be added).
I spose you could go so far as to increase the 15pt weapons to 20pts each and the 30pt weapons to 40pts each?
I’m not in favour of hard limits on the weapons loadout.
I’d far rather be able to select the weapons I want and pay an appropriate cost for them. I think that it looks better if every weapon has a cost and that 
may reduce the need for a 
multiple same weapon surcharge.
Cheers,
Steve.
