Is there any way to get the value of a variable based on the typepath of the containing datum?

Unfortunately no. A new form of initial() which took two arguments (a path and a var name) would be incredibly useful, but does not exist.

Short and direct answer, no, as Lummox said. However, the answer is technically yes, since there is a way.
var/list/initial_variables[0]
proc/setup_initial_variables()
    var
        datum/D
        list/L
    for(var/type in typesof(/datum))
        D = new type;L=new
        for(var/V in D.vars)
            L[V]=D.vars[V]
        initial_variables[D.type]=L
        del(D)

world/New()
    setup_initial_variables()

proc/initial_from_type(type, variable)
    var/list/L=initial_variables[type]
    if(!(variable in L))return 0
    return L[variable]

Just use the initial_from_type function, passing in a type path and a variable name.
client/verb/test(type_path in typesof(/datum),variable as text)
    src<<initial_from_type(type_path, variable)
