Diastatic malt powder substitution

Diastatic malt powder substitution

Planning to make these for tomorrow’s dinner :  http://www.wildyeastblog.com/get-your-malt-on/

Poolish is started, but  I don’t have  – and cannot get it where I live  – any diastatic malt powder, was thinking of replacing some of the strong flour with malted wholemeal – has anyone an idea of how much I could replace and if it could work?  

Thanks
