Conceptually, no. An image recipe is a recipe. Global data is global and
local data is local. A recipe (image or package) set local data only.

Correct way is different distro or machine. Obviously the build impact
is high for such as small difference in images.

Two possible hacks to me:
1. package10_1.0.0.bb and package11_1.1.0.bb but then you need to manage
the dependencies inside recipes (those (r)depending on package10 or
package11). If it's a "final" package which isn't a dependency of
anything else except the image, that's actually not too bad. Then in the
image you add package10 or package11.

2. Have an intermediate recipe which RDEPENDS_${PN} += "package
(=1.1.0)" and the other on "package (=1.0.0)" and install this
intermediate recipe in the appropriate image.

There are shortcomings in both hacks (otherwise they wouldn't be called
that way :) ).
