I have though about changing the neckline to a tshirt neckline. I don’t have the pattern yet but I would cut the back on the fold and use an existing tshirt pattern I have, either an Ottrobe or Make It Perfect basic tee, but flashback skinny tee would be fine too, to redraw the neckline and then add a double folded stretch band like finishing the neck on the field trip. I probably won’t use the Field trip raglan as it is a raglan and therefore the shoulder pieces make up part of the neckline, I would choose a tee shirt pattern with set in sleeves as it will be easier to borrow the neckline. I also have plans to do this to a knockoff puppet show knit dress.
I have one of those massive metal snap presses by KAM, it is amazing! I use it on everything and I rarely put in a button now unless I feel it helps the aesthetic like a coat or Good clothes. The press is expensive (about $100 in Australia) but once you have one the snaps are so cheap, like $3.40 for 100 (200 caps, 100 sockets and 100 studs). I figured once I had put snaps in about 20 garments I would be ahead. I have used the press so much, I even fixed a dozen or so cloth nappies where the velcro was no longer working saving a friend having to buy that many more cloth nappies. If you can swing the money a big snap press is So easy to use and well worth the money.
