The strategic benefit of faster movement is a huge force multiplier. It would be crazy not to incorporate streak drive into larger ships so long as it's reasonably safe.
Defensively you have faster response times.
Offensively you spend less time travelling and have a quicker response rate to opportunities.
Operationally you can cycle units back to home base for maintenance cycles quicker. You can transfer units quicker.
Even if you take a mass penalty that means you need to chuck out some grasers or 5% of missile storage etc. it would still be worth it. You can delete the 'just in case' grav lance they fit on Manticoran SDs and put that space to good use.
Could you please RTFM? The Andural class was the only SD with a grav lance. The 14 hulls built were all retired by 1918.
The other point here is that the only existing example of a streak drive is approximately twice the size (volume? mass? number of hyper-gerbel wheels?) and capital ships have armor around their vital systems. Replacing a vital system with one that occupies more volume would require a pretty fundamental redesign of the core vital systems as well as cutting through super-dreadnaught class armor. Ain't gonna happen. Cheaper and possibly faster to build new SDs with all the new bells and whistles.
Now on new construction, I'd imagine that they'd leave some space for an upgrade in place --- assuming that Dr. Simoes knows the volume requirements, which isn't a given. He's specifically said to not know much about the actual hardware.
Now, on smaller ships an upgrade is more practical, but it would still require a pretty thorough redesign, and BuShips might well decide that incorporating it into new ship classes rather than doing expensive refits is the optimal way to go.
Of course, if Dr. Simoes and the rest of the team at Bolthole manages to come up with a design that fits in the same volume, then upgrading everything in sight would be a no-brainer. I'd imagine that would be a fairly high priority design objective, but not meeting it wouldn't hold up the project.
