Configure Starting Loadout, a Menu Helping Sidegrades and Survivalists

With the 464 SPX and HZ12 coming, and the Survivalist still somewhat lacking, I think there should be a new "configure starting loadout" menu added to help the use of those and more. A mockup:

Survivalist
Survivalist particularly could benefit from this menu. If you're sacrificing playing a real perk for the sake of "mix and match", a random spawn weapon and a couple grenade types lumped in as side effects of skills you might not want is kinda crap: stuff you don't want makes survivalist somewhat "mismatch" or "all mix and no match".

Tier 1s' equality is supposed to be good enough that survivalist should be able to take whatever he wants, without any more to it than that.
Grenades are less equal, as part of other perks' pros/cons, and that's fine, but for survivalist to balance that and not just encourage the best types, the max you can carry should be adjusted depending. Carry 4 good(namely med) grenades, or 5 others. Or maybe 5&6.
Knives aren't important to choose between with the current options, but some may find it appreciable.

Sidegrades
The configure starting loadout menu would not have to be exclusive to Survivalist. Other perks could still be limited to spawning with their own stuff, but with more content, they'll have things they could choose between.

Tier 1 multiple options are getting added, we've apparently already got the HZ12 coming to Support Specialist's arsenal for 200 dosh. When that's added, plenty of people will be willing to buy it wave 2/3 just because it's the fresh new thing. But eventually if everyone's spawning with the original tier 1 and the other tier 1s are balanced and generally for the same role, they'll be overlooked in favor of progress to t2+. Players choosing which to spawn with could make tier 1 sidegrades more worthwhile.
Grenades are another opportunity for future sidegrades. For demo, it could feel especially fitting to have options there.
Knives' spawn melee slot could even get some sidegrades. This wouldn't be worthwhile if they were just more knives that worked the same way, but they could add appreciably different weapons to the slot. For example, there could be a nightstick available to SWAT, surv, and zerk, that has weaker damage than the knives, but better reactions, maybe altfire could even stun sirens and husks.
Spawn pistols could also get more options than the Beretta 92. For example, a Hi-Power with 18dmg and 13rd mags.
