Gonna be honest, most of the X-Pulse and Blasers don't seem like they'd be that Attractive to me, unless they'd get major changes from what you see in the TT weapons.
The first reason for that, is because one of the big things IS lasers in general have going for them is good damage/heat values. This is important since IS mechs cannot boat as many heatsinks as clan can. Any weapon that has compromises on that front is going to be a pretty tough weapon to be effective with, unless it offers some other dramatic advantage. (Like exceptional range, PPFLD, or some other aspect that isn't available elsewhere.) For example, take that Blaser - Not only does it compete with the clan HLL in terms of design, but at 9 tons, 4 slots, it also almost directly competes with the Heavy PPC - a 540 yard, PPFLD weapon. Just what is it going to have to look like to compete with that? Something FAR different from it's original TT values, i would guess. If this were the only problem, it probably wouldn't deter me, though, because most weapons are fudged here and there, and you could tune them to do what they do appropriately.
However, there is a second thing that concerns me - What new weapon, role, etc would you like, and/or expect these weapons to fill? For the civil war, you found that most of the added weapons (that didn't just flesh out a set) did something not yet accomplished - Examples include RACs with amazing DPS, and dramatic drawbcks, ATMs that created there own niche, or even Heavy lasers that pushed clan laser alphas on the into the stratosphere for many mechs. This contrasts with something like a blaser, which, if you go by the tabletop lore, is going to be very much an either/or when comparing it to a pair of large lasers. It's either going to replace them in-masse because they are tuned to be better, or no one will use them at all, since the two weapons would compete for almost identical roles. Lasers are one of those weapons that need a little more defining already, and adding more, very similar when boated weapons to that mix just creates more confusion to that mix, which concerns me.
If Anything, new IS laser options, like blasers and X-Pulse, need to be more radically different than other IS lasers - Think more along the lines of Large X-Pulse lasers only dealing light damage, but with sub 2 second burn+Cycle times. (Like a LXPL looking like a laser AC5, or AC2) or Blasers that really do look like exaggerated heavy lasers. (This means having the damage to match their massive tonnages, likely pushing out to previously unseen laser damage values.) Whether these types of idea stray too far from the lore is obviously a potential issue here, but i can't think of a way they start to create new roles, and thus avoid either being unused, or pushing other weapons out, without being that different.
