Repurposing mag pouches on surplus TAP chest rigs for other equipment?

So Tap rigs seem really cool for minimalist setups and easy to dye. The thing comes with 8 mag pouches However i only want to run 2 .556 magazines, which i plan on getting KYWI inserts for. Thing is, I’m worried itll look a little goofy having 2 of 8 mag pouches filled, and im worried that equipment Amount to the empty pouches might try to hang outward. Are there inserts i can get for the following equipment that i could use in the mag pouches (or even things that would normally go in the medical or admin pouch)? The 37mm shells perhaps?

Heres the shit I wanna run:

2 AR Mags

1 Glock Mag

1 Radio (Mabye)

1 Surplus Admin Pouch

1 Surplus Medical Pouch

1 Torniquet

1 Shotgun shell caddy for 5 or more shells

2-5 37mm Shells
