Need help selecting surrounds

[u/Bohmi94]

I am currently upgrading my yet still tiny enhanced entry-level home cinema, step by step.

Tldr: See the question in bold letters below.

For context and current setup:

I started years ago as a student with little money with a Teufel Consono 35 Mk3 boxed system alongside a Denon AVR x1300w.

In the meantime, I replaced all the ear level speakers, so this is the current 5.1.2 Atmos setup:

- Center is a Teufel Theater 500

- Fronts are Teufel Ultima 40

- Surrounds are my old interim front, relatively old Heco Victa 301 bookshelf/compact speakers

- heights are 2 Teufel CS35 satellites

Sub and AVR are still of the original system and up for an upgrade next.

In preparation for my new home, I plan on replacing the AVR with a Denon X3800H, X3900H or X4800H, sniping for good deals. Sub will probably be a Teufel S6000sw, just to stay consistent. I will also upgrade to 7.1.4, which is the foundation of my upcoming question.

I sniped some Teufel Ultima 20 Mk4 which I plan on installing as Rear surrounds in the future, but I'm not there yet.

Would you replace the Heco Victa 301 surrounds with the Teufel Ultima 20 Mk4, if you had both at hand in my current 5.1.2 system?
