Yea I'd be tempted to do that realy although if your going to the expense of a g40 lump do your reasearch and find the best lump for you and how you like to drive as there is alot of other viable options that make economical sense aswell, I'd also consider a kr on carbs quite cheap can make 200bhp and pretty simple well worn route sound great and probably a bit more retro suiting the car, or there's the 1.8t bit kore expensive and more involved conversion, or maybe a abf lump 150 bhp straight outa the box and engine probably costs a few hundred squids . Although if you want forced induction consider the g60 or g40 as options.
