I think that would quickly result in way too many combinations/password candidates.
It of course depends on how small your wordlist is.
If the wordlist is very small you could for instance just generate ?a[word] with the --stdout option of hashcat
and later on use combinator or combinator3 and e.g. pipe it into hashcat (or if very small even generate a new dict out of it).
If the source dictionary is very large, it might soon get infeasible to try each and every word combined with each other and furthermore append a random byte before each word.
