Why? The Arjun is heavy because it is more heavily armoured than the tin cans which gives the crew a lot more protection. The only weight reduction that can occur is if the DRDO manages to develop a lighter 1500hp engine or we manage to beg/borrow/steal the new 1500hp Leopard engine from the Germans. And that would not be a significant reduction, neither is one needed.
And you cannot reduce the dimensions of the tank without redesigning the whole thing.
The Arjun does need a few upgrades like a BMS, Commander's Independent Thermal sight, APS, etc. which can be incorporated in the Mk2. Please don't rehash the old "big/heavy" argument. It is a red herring. The weight and dimensions are as per the Army's GSQRs.
It is heavier for a lot of other reasons than the Armour alone. More importantly, there is no ERA externally, which means that the tank will be heavier by a tonne atleast. a sloping armour can reduce the weight significantly while keeping the tank well protected.
I know the dimensions are per the GSQR, however, imagine what a reduction of 5 inches in width can do to the weight.
The weight also has to do with the transmission and its components which can be made lighter by using new age materials (read alloys which are llighter but have the same characteristics of current materials).
That is the main reason why the Mk2 was envisaged.
Moreoever when I talk weight I am referring to the logistic backbone that is required to support this tank force. Tank transporters for example, road bridges, rail bridges, Rail carriage width, etc...This will take time to develop...MK2 will be a tank with active protection in addition to the current armour...which will also reduce the weight.
I am not rehashing the weight argument, but we live in the real world dont we?
