Arrow SLC - Will it crack??

I need to lbring a cinder block step up to level with an adjacent concrete floor so that I can tile both surfaces. The cinder block is only about half an inch lower than the concrete and I want to tile over both. I'm concerned about using SLC over the block - will a half inch layer crack over time, especially where the block and concrete meet? If you don't understand what I'm talking about, check out my pictures at this URL:

My initial thought - posted earlier in a different thread - was to install 1/4 inch Hardi backer over the whole entryway so I didn't have to worry about cracks.

Thanks!!

Prime it and use the SLC if you like, or build it up with modified thinset, let it cure then tile over it, good idea to place an isolation membrane over the area where it connects to the old slab or a align the tile so there's a grout joint over the transition, then caulk that joint with a matching color.
