I do not know what you have in reality for those 1k on weight. Now, with those basic modules around, you have a huge deficit on energy regeneration and cooling regardless maxing out those on your picture. Having some around, you can go just for the basic. Not have to be but might help out with better stability. Sorry, I do not have windigo maxed, but numbers will be much better.
your second will be bad as well maxing modules. You still have some around that can help a bit better.
It is not the best not knowing the full set up. Now, having tons of weapons do not translate into more effective mech. For now, just for basic it is ok below. Now, that can change if you also increase the energy cap and heat cap with those not premium. That can give you a bandwidth on the high end with little energy regen and cooling.
The biggest issue it is the need of maxing those module parts. As I mentioned before, it is ok to make weapons, but you need to balance with modules set up. Maxing weapons, torso and leg will put you up against tougher players. Modules need to be hand to hand. Do not get focus on weapons right now. You might have to change them with other modules and will be maybe a waste. Modules are basic to go for if have them.
Also, use properly the worthless epic parts to make legendries for transformations. All can be change based on how you do prefer to play. If you are counter base or balanced base player generally speaking.
