Question about making sock a bit larger

I was wondering if I can make the sock larger by increasing the stitches by 5 since the lace pattern is a 5 stitch pattern. So instead of 50 sts it would be 55 for the next size up? I am also using the magic loop so the K2tog isnt necessary for me to do (at least I dont think it is). Is there anyone else making theirs larger? Thanks.
