So after going through my Models the other day I have 3 built Penitent Engines, 1 built Mortifier, an unopened Penitent Engine/ Mortifier box, 6 Arco Flagellants, 17 Repentia, 2 Repentia Superiors, and both Blackstone Fortress Priests, plus a custom one.  So enough for a Penitent Host Detachment.  I need to get a few more models to round it out (I would like more Arco Flagellants) and want to convert multi piece Canoness into a "Repentia Canoness/ Palatine"
