I see two issues here, perhaps separable.
1. Use of inline data.
This can be accomplished by adding support for the data scheme.
Examples (from Fujisawa-san):
<object height="20 mm" width="20 mm" type="image/jpeg"
data="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . . ">
Example Image
</object>
or
<img height="20 mm" width="20 mm" alt="Example Image"
src="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . . " />
2. Separation of the data from the reference
This is where the declare attribute comes in. I went back and read
http://www.w3.org/TR/html4/struct/objects.html#h-13.3.4
It seems to me that the declare facility would let a client supply the
content for the object before its reference, not after. If the requirement
is that the client can send the image data at the end, I'm not sure that
HTML supports that.
If there is a requirement that the client can send the data first, then
refer to it, then an example (again, thanks Fujisawa) is:
<object id="image_1" declare="declare" type="image/jpeg"
data="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . . ">
</object>
. . . .
<object height="20 mm" width="20 mm"
data="#image_1" >
</object>
I think the first requirement is good to have, but we can probably drop the
second, especially since the ordering is probably not what we want.

I don't understand the intent. I you want to get actual image data later
(not at the declaration), you can just use 'img' or 'object' element
without 'declare' attribute.

The following example shows one type of separation, but I don't think
that meets your need.
<object id="image_1" declare="declare" type="image/jpeg"
data="data:image/jpeg;base64,aGh67Fghsapa0Hji7dfGSweTa . . . ">
</object>
. . . .
<object height="20 mm" width="20 mm"
data="#image_1" >
</object>
