Note that the above list specifically avoids things that are also usable as adverbs. These commands show there are additional things whose role as an adverb does not preclude it being used otherwise:
$ awk '$3 ~ /ly$/' $t|grep -v adv|wc
    193     775    4354
$ awk '$3 ~ /ly$/ && $4 ~ /adj|n|[^d]v/' $t|wc
    204     818    4667
Here are those:
$ awk '$3 ~ /ly$/ && $4 ~ /adj|n|[^d]v/' $t|grep adv
1 3676 bimonthly (adj,adv)
1 3767 biweekly (adj,adv)
1 6026 cleanly (adj,adv)
1 13037 fortnightly (adj,adv)
6 18738 likely (adj,adv)
1 19524 mannerly (adj,adv)
11 140 only (adj,adv)
2 24359 poorly (adv,adj)
0 28421 semimonthly (adj,adv)
1 33840 unmannerly (adj,adv)
2 35157 weakly (adj,adv)
1 35436 willy-nilly (adj,adv)

Also, perhaps of note is that in the FRELI data, only a small proportion (2123-1713)/2123= 19% of adverbs end in something other than ly:
$ awk '$4 ~ /adv/ {print $3}' $t|rev|cut -c1-2|rev|sort|uniq -c|sort -n|tail
     11 to
     13 se
     14 ng
     14 th
     15 ce
     15 rd
     18 ds
     24 re
     26 er
   1714 ly
