Firstly -
Without going into great detail it does seem you may well have to have several options as there is a need for medium to even deep concealment. It's a hassle changing rigs but that may be your only way out.
Therefore, perhaps a clip type IWB for when you can use it but - quickly removeable. Perhaps too get used to an empty SmartCarry so it is there when needed. Pocket is quicker to adopt and change, so that is not too tricky perhaps.
So - seems like you will have to have choices to suit occasions - at least seems that way to me right now.
