Ohhhh right that's how they do it. Err I'm having doubts on if a full stock would even be able to fit on that since full stocks have the two sorta guides that might get in the way of the tube coming outta the lower.
Another option is to use a stock which has two battery compartments and build a parallel harness. I have a CA Vltor MOD stock that allows a battery to fit in both the left and right compartment. I'm sure many crane stocks are similar. I built a short parallel harness that connects both batteries to the buffer tube wiring. This way I can run two 1100 mah lipos together for a total of 2200 mah. You need two batteries that are similar in size and in similar condition for this to be safe, but I have never run out of juice with that set up during a one day game. If you source the largest battery to fit the stock you might be able to get to 3000 mah.
This won't help your M4 be an M16, but provided you already have two good batteries all it will cost is a few connectors, shrink tube, and some wire. A hell of a lot easier than a receiver swap on a potentially off-spec rifle.
Keep in mind a receiver swap means your gear box needs to properly fit the new receiver. Not all of them are the same. Your hop up needs to fit the upper and not sit too high or too low which will cause nozzle interference. I bring this up because generally I've run into problems when swaping gearbox components into different receivers. Many times the "trigger sear pin" hole is different and causes the gear box to point high or low, or when the stock is threaded into the back of the gear box the nozzle end is pulled up. This doesn't always happen, but airsoft doesn't have any standardized industry tolerances. For example I tried putting an SHS nozzle in several of my M4's, was too long and didn't feed. I have a G&P M16A2 upper than will not fit on my G&P M16A4 lower without a rubber mallet and some swearing. Sure, you can usually mod parts to fit, just go into the receiver swap knowing you might have to.
It's not the cheapest option, but I would recommend buying a complete M16. It's just nicer to use and work on when the parts fit as they should. Ever seen those guys on the field who have to pull the trigger a certain way, have to have tape or Velcro on their mags for them to feed, or can't change the fire selector or it will jam? That gets old really quick.
