The 6020 is not near as common as the others, so may not be mass production worthy. But it won't hurt to contact http://www.maplehunterdecalstexas.com/ He may be able to help if you can supply some decent pictures.
To get to the manual sdunt posted, the link doesn't work for me if I click on it, but if I right mouse click and go open in new page, it opens up correctly.
Maple Hunter are pretty good to work with. Assuming the dash itself, is the same across the loaders dash dimensions, You could ask them to substitute some words (dash letterings) for something else. Changing letters or images isn't a difficult thing to do on a decal,, the difficult part is, if you say you'd want a new word off in the middle where it didn't exist, (Say, Oil Temp,) that sits over top a hole in the dash, that becomes a whole different process.
I've gotten custom made dash decals made for some of my tractors, and I suspect in US dollars, you'd be looking at around $200-$250 or so to get that done. It's a painstaking process. Once completed they do look great. For yourself, to recover initial costs, You could get 3 or 4 dash decals and sell them, to help recover original costs.
Here is an example of say a dash decal I had made up for me,, this one is quite customized though,
