Very likely No because This is Not just an MC issue but often Pedal and other problem(s). Might could do it but not easy. Yes, If you drive on the street at all then could have big legal problems and car insurance can void your policy after a wreck.
First, Smaller MC w/ stock system can have same problem as "GA upgrade" w/ OE MC. See my Cave,
Brake UpgradeSome Older cars, 60-70s cars, had non-boosted manual brakes as standard and PB as an expensive option.
And often had not only Different MC but different pedal parts too and many times not easy to switch in PB later.
Many had different pedal and mounting parts and mount was often welded dash frame element(s). Was done to add pedal leverage by moving top and MC pivots. You can move top pivot up and MC pivot down the arm so actual foot pedal is same height for either system. Typical PB pedal is ~ 4:1 vs MB pedal is ~ 4
.25:1 to 5:1. Even change 4:1 to 4
.25:1 makes a big difference in pedal effort to MC input pressure.
Others had some or all above changes and slaves in drum brakes w/ different bore size, different shoe specs, etc. to make a car will stop right w/ either setup.
Disk brakes, even Front Disk Only, Stop all of that and made PB required on nearly all cars after late 70's. PB often was needed just to stop w/ disk brakes to meet FMVSS rules.
You could get say Ford Pinto and other light cars w/ manual brake on front disk but became rare very soon. PB only on many heavier cars like "Station Wagons" w/ front disk. (Side Benefit, Also make it easier to make cars w/ one setup as reduces inventory etc.)
Not sure what you're trying to fit...
Race only car is likely to dump spare tire and mod or remove plastic tire wall so likely a "Cube" shape cell should fit w/o a lot of work... Need to support and/or move brake line to R-side caliper.
Problem tho is next to Radiator and fuel likely get warm to hot fast if race is long. Hot liquid can cause several problems and heat up F-pump too isn't a good thing. May not pass track safety inspections for this issue as hot fuel will pressurize the cell and/or "leak" a lot of fumes. Or rules may require heat shields etc. for a cell near the rad.
Note: Pressurize the tank/cell for any reason often causes problems for system pressure as acts as block return line from fuel regulator. Vacuum in a tank for low fuel etc can cause similar problems.
Is why Fiero and other tanks breath thru the EVAP canister 24/7. New cars often self test EVAP system (and why many trip DTC for a loose cap after filling) but still equalize thru EVAP can/filter somewhere in the car.

Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
