The idea isn't to be completely invisible as in regular stargate it's to use the concept of stealth as the USAF uses it ie the enemy can see but by the time they do it's too late. And sure you're not using them on major worlds of the System Lords but oh boy is there a long list of minor worlds that probably don't have the needed sensors which Mr. Indeed would know about a fair few of them and where they are.
It's an upscaled Leopard with 8 rapidly reconfigurable bays instead of 4 for mech and 2 for ASFs of a Leopard and a pair of small dedicated cargo holds as well. Oh and due note that the point defense it equally lethal against stargate fighters as it is missiles. But yeah I imagine escort variant that ditches the bays and maybe the cloaking in exchange for triple the missiles and double the railguns and staff Cannons and more powerful shields and say 50% more point defence would be a viable design. Maybe add the equivalent of say 4 sub capital missile tubes(ie smaller variants of what the Daedalus and Prometheus use but with ideally a few reolads) if you're only doubling the regular missiles
Plus its only inspired by a Battletech design and therefore not limited to the rules especially with Stargate super materials and engines involved so you could probably haul around the weight of a fully loaded B-52 as external ordnance if need be. Let the Goa'uld and Jaffa fear the words Arc-Light
And the sheer size of Goa'uld Empire and its restricted flow of information will greatly hamper the ability of Jaffa on say a random minor planet to be able to adapt to the situation
It also probably doesn't really help those poor Jaffa that the SGC will probably be deploying in at least Platoon sized strength when the possibility of hostile forces is present.
