Can I cut corners with a low-poundage bow?

I'm used to making simple but good quality longbows, usually simple diamond pattern, between 40-55 lb range. Lately, however, I've got a project requiring a handful of very low-poundage bows, like in the 20 lb range. I'm wondering if this lower stress would be more forgiving for me to get the project done quickly, and if I'm honest, a bit sloppily.

What are some mistakes that might be forgivable with a low poundage bow like this?
