Uh, no. You can gain a lot of survivability by adding plenty of small HRPs and engineer them. A good combination of shield and hull goes a long way. And that's not just pure theory and having fun, also a number of PvP players (i am not one, i just like to build tough as nails PvE ships) run hybrid setups with plenty of hull reinforcement packages.
[Sidenote: that's also to some degree based on SCBs and feedback rails. In PvE i can use SCBs quite fine, but when you try to use them in PvP, chances are that your get very little out of them, as your enemy will just rail them. But even I as PvE player often build for some hull durability. After all, HRPs don't need power, don't create heat and just do their job. ]
That all being said, those ships don't need or even want HRPs in the big slots. Look at HRPs. The bigger they are the less they offer compared to their size and mass. And that's even before looking at engineering, where again a higher number of smaller HRPs gain much more of a benefit than a few big ones.
The bigger internal slots are rather filled with MRPs and perhaps an AFMU. MRPs scale much better with size. (Although a combination of a big one to absorb the damage and a small one to boost the absorption rate also is very often seen and very powerful. )
That all being said: unlike many other suggestions, which would just add to even more power creep, i wouldn't really be troubled by this suggestion. Considering how HRPs scale, all this suggestion would do is adding some useless modules. It would bloat the list of modules and thus the database a little bit, but would not really affect balance.
