A longer-term project: Bringing some ideas together

Few conlangers (except engelangers and auxlangers) ever make isolating languages. I surmise the reason for this is that isolating languages are felt to have less of a potential for things to develop - the lack of morphology feels stifling, and all isolating languages are felt to be grammatically the same as Mandarin.

I have long intended to make an isolating language that differs from Mandarin and such without being too much like English either. So let me start out.

These features I have already mentioned will be included:

• Wackernagel adpositions under some circumstances
• Suppletive auxiliary congruence 
• As much of the indefinite pronoun thing as I can reapply to an isolating context
• Some impermissible possession
• Some unusual ordinals
• Something along the lines of verbal classes
• Implicative obviatives or whatever to call them
• A rich set of conjunctions

Seems like a set of features that could combine nicely and provide for a rich and detailed grammar.
