I have put together an excel spreadsheet to upscale all the major dimensions in increments of 0.1x up to 3x based on the 6 gal template. It calculates overall height, maximum diameter, the voulmes of the three main body parts and the total volume. This it gives you in litres, US Gal, UK Gal and sheng. Figures are shown in both inches and metric.
It shows you what the overall size will be so that you can pick a suitable scaling factor to apply to the 6 gal template. I did not bother with the arm as many folks might like to adjust that anyway to suit their own preference.
If you want a copy just pm me and if someone knows how to convert it to pdf and post it for others to use, please feel free to do so.
You still need to apply the chosen scaling factor to the template dimensions - I am not going to do it all for you

but it helps you decide which scaling factor to use for the size you would like to build.
For your info the 3x size worrks out to be 63" high, 39" in diameter and holds 185 US gal or 701 sheng.
