1. Verb to noun

Ation:

[[X] V ation] N

Transport → Transportation

Populate → Population

Exclaim → Exclamation

2. Noun to verb

Ify:

[[X] Y ify] V              where Y=N,A (noun, adjective)

Nouns:

Justice → Justify

Clarity → Clarify

Identity → Identify

Adjectives:

Pure → Purify

Diverse → Diversify

Intense → Intensify

3. Outcomes:

Transportationify, Populationify, Exclamationify

The resulting words are not well-formed and do not exist. What doesn’t seem to work about this process is the affixes. It seems you cant have 2 affixes put together. Ation and ify just doesn’t make sense. It seems in most cases, noun endings and verb endings don’t fit together. If we’re combining affixes for different lexical categories, we would basically be creating new words, a combination of nouns and verbs, like nerbs or vouns.
