I'm a little confused by your approach here. You want to use as many as possible of a 7 ton weapon, so you started with a 35 ton mech?
If starting with Ravens indicates that you want to go faster than 100kph, you're never going to quite get everything you want. You can get close, though.
I assume you ended up with a build
something like this. It does have ECM, which could be very useful for surprise sniping. If this is what you want to do, you should also try this somewhat faster
ECM Cicada.
You also have good options in
Blackjacks and 55 tonners, like this
Griffin or this
Shadowhawk. The 55 tonners probably offer the sweet spot you need to balance out speed and heat efficiency, and they can mount JJ.
In case you hadn't noticed already, "as many PPCs as possible" basically means 2, because of
Ghost Heat. It gets crippling if you try to add a 3rd. You could chain fire this
Shdadowhawk, if you want, but chaining 10 damage at a time is generally less effective than striking with 20.
EDIT: Technically, this
Blackjack has all the features you're looking for. This
Cicada is very close.
