Yep, they sure are. I did that to my Curl.
It really depends on what you need. I rarely use the saw on my multitools, so I personally wouldn't do it; however, if you need a saw, one would fit there. The Wingman scissors work pretty well. They're not the best scissors in the multitool world, but they suit my needs perfectly.
I documented my Curl mods - I found the first 2 stages, but couldn't find the final stage where I put in the Wingman pliers.Stage 1 : https://forum.multitool.org/index.php/topic,87912.msg2311808.html#msg2311808Stage 2 : https://forum.multitool.org/index.php/topic,87912.msg2430466.html#msg2430466
