As so many people have stated before me in both eloquent and rigorous fashion, upgrading all DHS to true 2.0 DHS would be a minor increase in efficiency that would benefit heavy and assault mechs most, as well as the very-high-heat weapons like the PPC, ERLL, and LPL. The simple fact is that the heat generation scale has been effectively tripled while the heat dissipation scale has not. Nobody who has even the most simplistic understanding of math should ever fear that boosting DHS output by .6 would make up for a 3x increase in heat generation.
There are two real fixes that I see happening to the underlying heat issues. The first is adjusting the time scale on which heatsinks operate. If a SHS dissipated 1 heat every 7 seconds, and a DHS did 2 heat every 7 seconds, suddenly a lot more builds would be viable.
Alternatively, shaving off one heat from the LL and 2 from the PPC, making ER weapons have +2 heat relative to their standard versions (rather than +3 or +4 or more as they are now), and making the LPL have only +1 heat (matching the increase of the SPL and MPL over their standard versions) should make the large, high-heat weapons much more viable without boosting the useability of the smaller (boatable) weapons.
In neither case does raising DHS values from 1.4 to 2.0 actually make all that much of an effective difference. It would matter more in the former case, but since at that point heat is being balanced by tweaking the dissipation time scale anyway, if 2.0 DHS are too strong just increase the time scale a bit at a time until a good balance point is reached. Incremental changes with time to see them in action across a large population base is and of a right ought to be the gold standard of balance tweaks.
