I am thinking about building a 22 Creed, or another 22 cal that has the capability to shoot 88-95gr at or around 2700-3000. Is this unrealistic? My only reasoning in using the creedmoor case is neck length and case capacity. Any thoughts or advice?

22 Creedmoor 1:7" twist barrel 90 grain bergers

Barrel length is no constraint to me, I'll go however long I need to maximize velocity.
Also, I did not realize a 223 AI gets that much more velocity than a standard 223. I have a 223 that I have had trouble getting over 2760 with any decent accuracy and I am only running 77TMKs. 21.5 of H4895, Lapua match brass, GM205 to be exact and that node is at 2730. Sorry multiple questions in the same response.
Oh, I haven't gotten into accuracy testing, yet... still playing with velocity. Regarding .223 vs .223 AI, I can't really comment given that I have not done much work with regular .223 and if I had to guess, my 90 gr .223 AI loads are well over recommended SAAMI limits. Nonetheless, reading the fired cases, I'm doing okay (not piercing/blowing primers, no sticky extraction, etc...). Running up my pressure ladder, I ran two rounds at each charge level and on the 27.4 gr load I saw an ES of two; not that it's terribly significant given the sample size, but it certainly looks better than a lot of other loads in that regard.
On my heavy loads (90 gr) using slow (for the cartridge) powder like 2000-MR, I'm running Remington 7 1/2 primers because of the thick cup and they're apparently quite hot. FWIW, 26.4 gr of 2000-MR under the Sierra 90 lit by the Rem 7 1/2 got me dead on 2800 FPS per the Magnetospeed out of the previously mentioned 26" 7-twist barrel.

Valkyrie or a 22 Br would get you there. If you wanted to wait a year or so I bet the 6mm GT will be getting necked down to a 22.
I've ran 90's in my 22 creed at both 3100 and 3350. Its a fun little combo.
I have a 26in 22-250AI, 7 twist. Very similar case capacity to a 22 creed. I shoot 90gr bergers at 3199fps and they shoot great. It will actually shoot them at right under 3400fps but I back them down for prs matches.
95gr sierras run about 3083 fps out of it but havent tried to run it up any higher. Both the bergers and the sierras have single digit sd's. Had first round hits at 1100 yards with them both. Bergers are 7.2 mil to 1100

Just loaded a ladder for my 22BR. From what I have seen, 3050 fps or more is possible, depending on what kind of barrel life you want to have. I went with a 26" 1-7" Bartlein, Lapua brass, CCI 450 or Tula for primers, H4895, and the 88gr ELDM. If I can find a node at 3000 fps with H4895 I will be happy. BC is very close to a 6mm 105 Hybrid. Can't push the 95gr SMK fast enough to gain anything over the 88 ELDM.
The go to load with Varget is 28.8 at .020" off the lands.
I am running the 75gr ELDM at 3025 out of a .223 Tikka Varmint 1-8" with Nammo brass, H4895, and CCI450's. My next barrel will be a 1-7" so I can play with the 80 ELDM. It will be a 223 AI too.

I had a tikka varmint just like yours a couple years ago, great guns!! I had the factory barrel set back just ever so slightly and reamed to 223ai. Gained about 150fps. Shot vanilla 223 just as good with the AI chamber as it did the factory.
My 22 Dasher is putting the 95s out at 3060
And shooting tiny groups. 6.5T 26” and a lot of freebore.
