I was wondering, is it possible to use string interpolation when using `readInteger`?

Try searching google, eg.
http://lua-users.org/wiki/StringInterpolation
http://lua-users.org/wiki/VarExpand
http://lua-users.org/wiki/TextTemplate

also check other google results.

One twist if apply in AA script, we may have to check the value type and if it is number type and integer, we may need to convert to hexadecimal string instead of just tostring, like some html template that some html escaping/un-escaping may be need.

yes.
local addr
addr = getAddrss(addy)
or
addr = getAddressSafe(addy)

if (addr ~=nil and addr ~= 0) then
local myValue = readInteger(addr)
else
print("addr is null")
end
