I just bought a Miniwave LED dive light and on my first couple of outings i was kind of disappointed in its brightness. What would be the easiest upgrade to perform on this light? I want to basically just changing out the emitters. This will be my first mod to a flashlight so I was hoping for some guidance on what kind of emitters to get and from where.

The easiest is to just swap out the LED for the latest and greatest bin LED.
Next step is to change the LED and optic to the best available ( XP-G seems to be the flavour of the month).
Next step is to up the current supplied to the LED but then you have less run time and less reliability die to heat build up.
But the best step is to just buy a much better light or better host to modify.

Unregulated XP-Gs can be very bright, for a very short time.
Cutter or DX can supply XP-G's
Identify the LEDs that are in use at the moment.
Measure the current going to them.
Work out how much more heat can be generated before you run into problems.

I tried with with the original halogen version using a drop-in Terralux and extra heat sink.

Pack is right...it is a poor choice of housing to upgrade. The trouble is, for all its generous diameter it is a poor heat dissipator to the surrounding water. Plus, the batteries are in the same compartment as the light source, so will be absorbing all that unwanted heat and slowly cooking.
With 4 C Cells I'd swap-out to 25500 Li-ion's and configure for 2S2P, 7.2V (they state 5Ahr but it is much less than that, especially with your planned high 'C' rate draw). Then put in whatever LED, optic and driver you want, and if possible thicken the metal base for heat dissipation.

I also have a miniwave LED and was looking to replace the LEDs with blue ones to be able to look at fluorescence on coral reefs. Can this be done and if so where can I get the LEDs to do it?
