[Spaceships] Is This Legal?

In particular it screws the calculation of "miles per second per tank of fuel". Fuel is never measured in Spaceships as anything other than "tanks" or miles per second". Never convert fuel tanks to tons, lbs, gallons or hogsheads of fuel when calculating performance.

It also screws up the bonus you get for having many tanks of fuel. See "Delta-V increase" on p.17 of Spaceships I.

This. Also note that engine performance in G and dV is constant regardless of whether the ship is SM +4 or SM +44; a larger engine requires larger fuel tanks, but the net performance is the same.
