Agreed, it's gonna be a pretty much uphill task for OP.
If the OP doesn't plan to get any form of residency for his wife, nothing to stop him though, like a Close Singaporean friend is forced to do: Married a WP holder, wife living in JB, husband visits on weekends, once every 6 months or so, wife can come to Singapore for a month to visit the child, and then go back to Malaysia.
