I am not 100% sure but I have some wool which is a 2 and I needed a 4 so I double stranded the wool. My LYS said you can do that but you might need to go up a needle size. I did a gauge swatch but upped a needle size than the pattern called for and they were right because the swatch was the correct gauge for the pattern. So I am assuming that you will get bulky but up the needle size. As for felting I can’t answer that as I don’t felt yet.
I am using a chunky right now on a pattern that called for a worsted. It has made the size of the garment larger (which is what I wanted). I don’t know if you could use two strands of worsted to make a bulky, perhaps one of the more knowlegable knitters will be able to answer you.
When your ? craps out on you (it means you need to reboot) use the shift key and click on the symbol ^ and you will have a ? instead. This happens to me all the time.
Generally, you can use two strands of worsted yarn to equate a bulky weight yarn. However, you should do a gauge swatch to make sure you are achieving the proper tension the pattern calls for, especially since you are subbing it for another brand of yarn you are not familiar with.

Just a note for you: SWS felts very well but it felts very quickly. It will probably work for you used double and if the actual finished size doesn’t have to be perfect, go for it. SWS has some beautiful colours.
I think I am going to hold on that project for a bit, I want to get this just right, and the SWS wasn’t as much of a sale as I thought it might be…
I picked up some Classic Merino something er other, not nessissarily for that project…but just cause I had $10 of free that I could use on Michaels! winks
