The whole point of diluting your water is to reduce the minerals. To add minerals would be the opposite of what you are trying to do. Unless you were deficient on certain minerals to begin with while others were high. For example maybe your calcium, magnesium and bicarb levels will benefit from dilution but your sodium level and sulfate are already low. By diluting the sodium and sulfate levels even further with distilled or RO water you might need to supplement them with some minerals. This is obviously a hypothetical situation as I don't know your complete water profile. Hopefully you have all the necessary mineral levels (Ca, Mg, Na, SO4, Cl and HCO3)
I would suggest using beersmith if you have it or brewater (free program). Both of these programs will allow you to enter a water profile that you want to hit such as Pilsen or whatever. Based on what you want your profile to be you can easily adjust the program by diluting the water or adding minerals to see how you can emulate that water. Very easy to use and I would not personally change my water without using either of the two. I'm new to this though.
