Ive not checked the KJ count, but apart from that Id say you need to get the weight down.

Armour 40 kg
LEMs 9 kg
Disc 27kg
Batts 6 kg
Wheels and gears 10 kg

For Mounts, electronics etc. 8 kg is not much, and you need twice the amount of cells you have now really.

Given the dimensions you gave on the disc, it would be 5 cm thick. you could halve that, making the disc somewhere around the 15kg mark (it would still be 1 or 2.5cm thick), and use the remaining kgs for batteries and mounts etc.
