Conversion: MP5K to MP5??

[EAGLE_ONE]

Hey im new to this forum, but ive been wondering for some time, would it be possible to convert a Galaxy MP5K (Tokyo Marui clone) into an MP5 of some Variant? or ad stock and/or foregrip? i would just like to have the option to convert the weapon to a larger smg that has more stability. Thinking this through i have come across a few flaws in the conversion and needed a second or more professional opinion about the matters: one, the upper receiver and the barrel are much smaller than a regular MP5, would i have to change the upper body and or barrel?? and two being: The locking pins, keeping the stock plate on and the foregrip on an MP5K are different to any other MP5K. It would be very useful to here any comments on the matter and would be greatly appreciated. ANY IDEAS ARE WELCOME thanks

possible, but all that would be from the original MP5K would be the pistol grip and motor. new upper, front and barrel are all in order.
