So given the current system I would do the following:

1) create a generic form of the model without parameters set - a
broken model in one sense
2) add these other models that are different parameterisations of this
model as variants of this generic-ish one
3) add the existing apical cell one in as a variant of this generic model
also.
4) put an HTTP redirect in for the old URI to point to the variant form.

I take it the existing one is:
http://www.cellml.org/models/bondarenko_szigeti_bett_kim_rasmusson_2004_version01

which actually says:

"The model includes parameters for both the apex and the septum
regions of the heart (the apex parameters have been substituted into
the CellML version of the model described in )"

Which I find confusing.
