I agree with Bill, no problem with the slight size increase especially given the focal ratio of ƒ5.05.
To ensure a fully illuminated non-vignetted field make sure you have a focuser with at least 2.5 inch inside diameter base.
There is a web-app on the stellafane web site which lets you input the construction parameters, do ray trace check for vignetting & optimise baffle locations.
