I like this! When I was first looking at doing MFW last year, I thought I wouldn't be doing the history cycle 3X. But you really could.
Correct me if I'm wrong...
The basic timeline for a history cycle a la WTM is:
Creation to Christ (5000 BC-400)
Middle Ages (400-1600)
Early Mod Times (1600-1850)
The Modern Age ( 1850-Present)
You could schedule it like this---
Year One:
MFW 1st grade
for Creation to Christ up to 1600, using SOTW 1 and 2, you could supplement with SOTW CDs and use SOTW1/2 book recommendations to add in book basket. You could actually spread it out longer if you wanted to go thru the summer.
Year Two:
MFW Adventures (1600-1850), then supplement with SOTW3 CD's and recommended books for book basket and spread it out over the summer.
Year Three:
MFW ECC you could supplement with SOTW 4 CDs and Book recommendations.
Then you'd be ready to do MFW's history cycle making it your second rotation.
In both SOTW and MFW they say that their recommended books are to give you an idea or a starting point. Both say that they encourage you to use things you find on your own.
And also WTM says that the first cycle is just an introducation, it is not to give an exhaustive detailed history course in the grammar stage. It's just to "make pegs" to later hang information on in the logic stage. The first rotation is just to expose your child to these stories and introduce them to the info. The logic stage is when they will start asking the why and how of everything.
I have to agree with the other poster that said that MFW's history cycle was harder for the lower grades. IMO, after taking a detailed look at the books used, it is definitely more of a logic stage program.
If you did not mind doing SOTW twice. You could do SOTW for the grammar stage, and then save MFW for the logic stage. But then you'd be missing the AWESOME bible that's tied in when using MFW.
Another thing to think about to is that depending on what latin program you chose, like Lively Latin, they are going to read and learn from the Middle Ages period. You could use that as a resource. And if you use WWE and add in your own dictation and narration you could also pick up some gaps with using history information that is studied in whatever time period you are in.
Does that make sense?
