[RMVX ACE] [RM2K] SMALLER SCALE CHIPSETS IN VXACE?

I've just received a copy of VX Ace and was hoping to create a game using the same size tiles as in 2000 as I have amassed large library of original graphics in that ratio for other non-rpgmaker projects (making use of the full colour ratio). I see that VX Ace uses boxes roughly four times the size (squared) of 2000 and wonder if there is a way to still use these old resources within the maker?

So it's rescale or redraw - hmmmmm maybe I'd be better off creating more up to date versions of elements as I use them anyway - I don't feel up scaling would give the quality of finish in after
