3x8 setup (crankset, chainrings, cassette) - lower end gear - trade for platform pedals

I have upgraded my kid's bike to 1x10 setup so I have all those parts that I pulled available. Posting it here in case somebody has a frame and wants a cheap setup for his kids, to replace a broken part or whatever.

Truvativ X-flow crankset with triple chainrings
Shimano 8 speed cassette
Alivio RD
Acera FD

I have the shifters with integrated mechanical brake levers but the cables are cut and a small piece that screws by the cable entrance is missing. I can include that too. I also have a free but crappy Capa fork (26", 80mm travel I think).

This is bottom of the list gear so I am not trying to sell it. Would like to trade it for some platform pedals in decent shape. Red color is a plus but not required. :) That's the last piece that my son is missing on his upgraded bike.
