"friendlylike" and "friendwise" have different meanings and usage contexts, but I wouldn't use "friendlywise" except in an unusual context. "friendlylike" is used because the adjective "friendly" already has an -ly ending which makes the corresponding adverb "friendlily" sound clumsy, so e.g. "I spoke slowly and friendlylike to him". We could use "friendwise" to introduce a context, e.g. "Friendwise, I don't have many, but acquaintancewise, I do". But "friendlywise" requires an unusual adjectival context, e.g. "I show different behaviors for different situations: suspiciouswise, on the train or in the mall; attackingwise, on the sports field; friendlywise, at work or in karaoke." It sounds very contrived though.
