Ok so going on this ......
-Larger than the Excel but smaller than the Ambie?
-Firepower CA,BC, or BB ?
-In Service: 2280's or 90's?
Yes agreed F_W the D7 K'lode's sold to the Roms in the mid 2260's IIRC were mere shells,
Hence this concept.....
OUTALANCE SHIPYARDS
C-10 TypeLate TOS/Early TMP Era Romulan Warbird Prototype
Owner: Romulan Star Empire
Class: Heavy Combat Vessel
Availability: Unlimited Deployment
In Service: 2265
Out of Service: 2290
C10 was the Starfleet designation for a class of Romulan Warbird in the late 23rd century.
Refits and upgrades kept the original KR7 an effective combat vessel throughout most of its long service life, but by the mid 2200s the Federation was fielding designs such as the Constitution class which considerably outclassed it.
As a result, the Romulans fielded a modified version of the ship during the 2270s.
This variant shared the same basic hull form with the original vessel, but included various detail changes including the edition of a second primary hull, combined with redesigned nacelles that increased the top speed.
The armament was also boosted dramatically.
Despite the changes, the C10 was still not a match for the Excelsiors.
Several skirmishes occurred with the Federation during the 2280s, generally pitting the C10 against the Excelsior class Starships.
The Federation design was generally the victor in these encounters.
Which I think is a logical upgrade for that era, the above design is the Romulan attempt comperable to a Light BC but only 230m in length.
Based on the hull used, as the KR7 would have been the Rom CA of the mid 2200's (obviously).
Now for my version .....
OUTALANCE SHIPYARDS
Vellius I.R.X. 1900 A-type WarbirdLate TMP Era Romulan Advanced Warbird Prototype

This early prototype, became foundation for the D'Deridex-class Warbird B-type.
This vessel class would become known by Starfleet as an A-type warbird.
These vessels are somewhat larger and more massive than Federation Constitution and Excelsior-class starships, measuring approximately 500 meters, and are believed to have a greater combat firepower, although they suffer from a comparatively lower speed capability.

Assigned to covertly patrol the Neutral Zone, also known by Starfleet as an A-type warbird.
These vessels are somewhat larger and more massive than Federation Constitution and Excelsior-class starships, measuring approximately 500 meters, and are believed to have a greater combat firepower, although they suffer from a comparatively lower speed capability.
How's this sound?
