Unless you are going to be doing
super-critical listening in Multi-Channel Audio (not multi-channel stereo), I would not be concerned about the change in Speaker for any Surround or Atmos applications.
Though controversial for some, there are arguments that even say the Center doesn't need to be a perfect match... but that is a can of worms for somebody else to open!
FWIW, I built my system around Music-first listening and specifically with Multi-Channel Audio in mind. My Mains are different than my Center, but as similar as can be with the similar Raal Tweeter and wide dispersion Mid-range driver... Tonally, there is almost zero difference between the three Speakers up front. My Surrounds and Rears also use the same Raal Tweeter and this was a deliberate choice because I do listen actively to 5.1 audio mixes including some that do not use the Front Center, but code for a Rear Center which is parsed to the Rear Surrounds.
More importantly, as I am not personally familiar with the Perlisten Specs, my recommendation is to make certain that there are no drastic differences in Sensitivity between the two tiers of their Speakers. It is important to keep as similar a profile as possible so that you don't need to cut the more sensitive Speakers drastically in order to give a less-sensitive pair of Speakers a fighting chance to be heard.
Room correction will also usually dial everything back to the level of the weakest link in the chain. If your mains are too strong, they won't get adjusted appropriately, while your weakest Speakers might even end up being boosted into positive trim levels. I have seen examples of this happening and it is not good for many reasons.
This may not apply to the Perlistens... as I said, I'm not familiar with them.
If your amplification is good, and sensitivity is within 3dB, I would not expect this to be a concern, rather just something to be aware of.
Out of curiosity, what are you using for Subs and what is your AVR/AVP?
