yes but if your going to go to the trouble just do it in carbon!` vacuum bagging is the way to go and isnt that hard. then you can you soaker matting that draws the extra resin out to make it lighter and strong. fibreglass is fine but id be using it for your first go just to make sure you get it spot on then do a carbon one. Making carbon trumpets for the race motors to awhile to get the plugs and mould made and workout the layers of carbon to use to get them light and strong, but well worth it in the end!
you can hire vaccum pumps and the bags are easy to get.
For a one off, shape it out of foam and then form over it and then melt the foam out with fuel.
makes for and easy one off mold.
