Esperanto question

In my Esperanto book, it says that the suffix -igxi means "become", and
says that this is also an independant verb.  For examples of the suffix
it contains such words as "edzigxi" = "edzo" (husband) + -igxi (become)
= "become a husband, get married (of men)", "edzinigxi" = "become a
wife, get married (of women)", "sidigxi" = "become sitting, sit down,
take a seat", "ellitigxi" = _el_, "out of" + _lito_, "bed" + -igxi
"become" = "become out of bed, get out of bed".  For the independent
verb, it gives the example "mi igxis esperantisto" = "I became an
esperantist".  My question is this: are the verb igxi and the suffix
-igxi interchangeable?  Can one say "mi esperantistigxis", or even, for
women, "mi esperantistinigxis", in place of "mi igxis esperantist(in)o"?
