What if, instead of inheriting from RealField(53), real literals inherit
from RealLazyField() ?
sage: a = RealLazyField()('1e-20')
sage: parent(RealField(200)(1) + a)
Real Field with 200 bits of precision
sage: RealField(200)(a)
1.0000000000000000000000000000000000000000000000000000000000e-20
sage: RealField(200)(a+0)
1.0000000000000000000000000000000000000000000000000000000000e-20
sage: RealField(200)(a*1)
1.0000000000000000000000000000000000000000000000000000000000e-20
